摘要
用静态法测量了甲醇在-30~60℃的蒸汽压,用Antoine方程拟合实验数据得到logP=8.28058—1688.39/(T-24.98)。甲醇的蒸发焓测量分两段进行:在-30~40℃,用LKB-8721-3蒸发量热计,在55~100℃,用LKB-8721-4密封弹反应量热计,并用方程△H_v=7.8542×(512.64—T)^(0.2906)较好地拟合了实验数据。
Vapor pressures of methanol are measured at -30~60℃ by using a static method ,and an Antoine equation, 1gP=8. 28058—1688. 39/( T—24.98),is gotten by regressing the experimental data. Enthalpies of vaporization of methanol are also measured by using a LKB-8721-3 vaporization calorimeter and a LKB-8721-4 closed bomb reaction calorimeter at the temperatures of -30~40℃ and 55~100℃resp. ,and the experimental data are fitted into an equation △H_v=7.8542×(512.64—T)^(0.2906).
